Fuel vapor expands in hot weather. Open the
filler cap slowly.
After refueling, close the fuel filler cap by
turning it clockwise until it clicks into place.
CAUTION
•
Do not refuel with the engine running

.
Turn the ignition off or to position I. If
the ignition is on, an incorrect reading
could occur in the fuel gauge.
•
Avoid overfilling the fuel tank. Do not
press the handle on the filler nozzle
more than one extra time. Too much
fuel in the tank in hot weather condi-
tions can cause the fuel to overflow.
Overfilling could also cause damage to
the emission control systems.

•
Keep your engine properly tuned. Certain
engine malfunctions, particularly involving
the electrical, fuel or distributor ignition
systems, may cause unusually high three-
way catalytic converter temperatures. Do
not continue to operate your vehicle if
you detect engine misfire, noticeable loss
of power or other unusual operating con-
ditions, such as engine overheating or
backfiring. A properly tuned engine will
help avoid malfunctions that could dam-
age the three-way catalytic converter.
•
Do not park your vehicle over combusti-
ble materials, such as grass or leaves,
which can come into contact with the hot
exhaust system and cause such materials
to ignite under certain wind and weather
conditions.
•
Excessive starter cranking (in excess of
one minute), or an intermittently firing or
flooded engine can cause three-way cat-
alytic converter or exhaust system over-
heating.
•
Remember that tampering or unauthor-
ized modifications to the engine, the
Engine Control Module, or the vehicle
may be illegal and can cause three-way
catalytic converter or exhaust system
overheating. This includes: altering fuel
injection settings or components, altering
emission system components or location
or removing components, and/or repea-
ted use of leaded fuel.
NOTE
Unleaded fuel is required for vehicles with
three-way catalytic converters.

If the fuel filler cap is not closed tightly or if the engine is running when the vehicle is refueled, the Check Engine Light (malfunction indicator lamp) may indicate a fault. However, your vehicle's
performance will not be affected. Use only Volvo original or approved fuel filler caps.
